I'm now working on another computer, and I have just realised how many things Autocad sets a certain way, which mostly I want to change.

For instance, VTENABLE. Hmm.....let me see...do I want pretty zooms or fast zooms? Set to 3 huh? Let's just chop that down to 0. That's better!

That is an example of a variable you can set once and it stays that way. There are others, which appear to be related to the drawing at hand, and for these I have a "blast 'em all" lisp that knocks them into the way I like them, at the same time sets all the layers that I use as standard.

I call this one Layset.lsp (It sets the layers!)- It does the extra task of creating variables for the layer names. You can see the variables, just at the top of the routine.

The plan here is that if you want to force something onto the "Medium" layer, then another lisp is used, mm.lsp and this makes use of the variable set up in Layset to change the item chosen to the preferred layer.

A while back I talked about specs for a new computer. Well, it arrived last Monday, bought by the place where I work. Specs, as far as I could tell, are 3 GHz, 2 MB ram, on board Intel graphics, 22" LCD monitor, running XP on a network. I assumed quite wrongly that my 2 year old computer, a core 2 duo at 2.66Ghz and an Nvidia Quadro 1500 ($NZ1000) would kick it's bum.

But no. It had near enough the same 3D performance, which I found after loading the same heavy drawing and running a side by side test. The test was not all that scientific, just shade the model and roll it around to see when it goes to wireframe. In general, I have found it a much snappier and nicer to use machine, apart from the lack of a second monitor.

I was peeved, since making all sorts of honking noises about on board graphics before it arrived. It may be part of my unlevel playing field is that I'm using Vista. Maybe I can downgrade to XP or the next windows?
